softhsm implements AES_KEY_WRAP_KWP but calls it AES_KEY_WRAP_PAD

What were you trying to do that didn't work?

Use the mechanism AES_KEY_WRAP_KWP (RFC5649)

Please provide the package NVR for which bug is seen:

softhsm-2.6.1-7.el9.2.x86_64

How reproducible:

Always

Steps to reproduce

1. Create HSM session AES key  (for blob wrapping)
2. Encrypt a blob(PKCS8 DER data) with session key (PKCS8 key)
3. C_UnwrapKey() the ciphered data to import a private key to the HSM

Expected results

Private key can be unwrapped and persisted to the HSM

Actual results

AES_KEY_WRAP_KWP is an invalid mechanism
